To all whom it may concern.-

Beitknown that I, ABRAM A. RHEUTAN, of Vorcester, in the county of\Vorcester and State of Massachusetts, have invented certain new anduseful Improvements in Mechanical Movements; and I do hereby declarethat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and in which Figure 1 is a side View, partly in section,of my invention. Figs. 2, 3, and 4 represent skeleton side views thereofwith the various parts in different positions to more fully illustratethe operation of said mechanical movement. Fig. 5 represents a plan viewof my invention, showing said invention applied to a feeding device forautomatically feeding forward sheets of paper or similar articles, ashereinafter more fully described; and Figs. 6, 7, and 8 are skeletonside views of my invention, representing its application aforesaid as afeeding device, the various parts being shown by full and dotted linesin different positions to more fully illustrate the operation thereofhereinafter described.

My mechanical movement consists of a roeking cam-lever pivoted betweenits extremities, a locking device at each end of said lever, a yieldingbody traveling within the are of oscillation of said carn-1ever andbetween said locking devices in first one and then the oppositedirection, and adapted to bear against the cam-lever or parts thereof,.whereby the said traveling body at each end of its reciprocation willcause the cam-lever to be unlocked atone end and locked at the oppositeend, thereby removing out of the line oftravel of said traveling bodyone part of the cam-lever and bringing within its line of travel anotherpart of said lever, as hereinafter described. Incidentally, too, a forceor power may be accumulated within the said traveling body, and suchforce or power may be released within the limit of oscillation of thecam-lever, and the said force or power when created or released may beused for any useful effect.

Hy invention when in practical operation is capable of imparting apressure or draft power to any mechanism connected therewith, ashereinafter described, either in a vertical,

horizontal, or any other plane, according to the positions occupied bythe various parts comprising said invention. It is designed moreespecially, however, to be applied to use as a feeding device, and thatothers may fully understand its nature and application to prac tice Ihave shown and described the same as being thus applied, both in thedrawings and the following specification thereof, said ap plieationserving to illustrate one of the many ways in which the power impartedfrom the device embodying my mechanical movement may be utilized whenapplied to practice.

To enable those skilled in the art to which my invention appertains tomake and use the same, I will now proceed to describe it more in detail.

Referring to the drawings, the part marked A represents the cam-leverhereinbefore referred to, having in this instance the cam-surfaces A Aupon the under side of each end thereof, and pivoted at its center tothe stationary bearing A extending up from the bed H. Any other form oflever may be employed to produce the result hereinafter described, andit may be pivoted at any point between its extremities instead of asabove described, if desired, without departing from the principlethereof. Both ends of the lever A are arranged to be alternately lockedwhen in a depressed position, as hereinafter described, by means of theswinging dogs B O, hinged at their upper ends to the stationary bearings13* O", and provided with the notches or shoulders B 0, against whichthe ends A A" of the lever A bear when depressed so as to come underthesame. A constant forward pressure is imparted to the swinging dogs BO to hold the latter against the ends of the lever by means of their ownweight or the springs B 0, one end of said springs being fastened to thepivots of said dogs, while their other ends are arranged to bear againstthe outer sides of the pins (4 a, fastened in the dogs. Therefore it isobvious that when one of the ends A of lever A is under its respectivenotch B or C it is held in said locked position until released therefromby pushing back its holding-dog and forcing up said end of the lever, ashereinafter described, the latter operation, as will also be seen,causing the opposite end of the lever to be depressed and looked, asabove described.

The cam-surfaces A A, hereinbefore referred to, are formed in thisinstance bymaking the lever A bow-shaped, the pivot of said lever beingarranged above the level of the holding-notches B (3 to accomplish saidresult; One end of the lever is unlocked and forced up, so as to depressand lock the opposite end thereof, as hereinbefore stated, by means of abody having a forward and backward reciprocating movement, and adaptedto travel and press against said lever upon the opposite side of theholding notches or shoulders of its locking devices hereinbeforedescribed. The above operation is performed by said traveling bodystriking and forcing back the swinging dog which comes in front of itsline of motion, and thereby releasing the lever, which is at once forcedup and its opposite end consequently forced down or depressed below theholding-notch of its dog, thus locking the same by the springing forwardof said dog, as hereinbefore described. It is obvious'that by thuslocking one end of the lever by the operation of unlocking its oppositeend a rigid cam-surface is brought in the path traveled by the movingbody at each reverse movement thereof between the ex tremities of thelever, thereby causing said body to be depressed at each of said reversemovements, and the lever to be alternately rocked in first one and thenthe opposite direction, so long as the reciprocating movement of thebody is continued. Any desired movement or movements may be impartedfrom the lever to said traveling body as the latter trav-, els over thehearing or cam surfaces thereof by varying the contour of said surfacesto correspond to the motion or motions desired to be obtained. The pivotof said lever may also be varied to one side or the other of the center,if necessary, to produce the desired result.

Power may be transmitted from the device by connection with either thelever or the traveling body, and said device may be arranged to operatein a vertical or any other angle or plane than that shown in thedrawings, so as to transmit motion therefrom in any desired direction.Said motion, it will be understood, always being either a pressure ordraft power, which it is obvious may be utilized in an innumerablevariety of ways ingoperating different kinds of devices and machinesprparts thereof-as, for instance, it maybe ni ployed for operating thecut-off of a steam-,

engine by connection therewith in any suitable and convenient manner, Itmay also be connected with a rack or lever having a pawl for operating agear or ratchet wheel, respectively, to in turn operate mechanismconnected therewith; or it may be used for operating a shipping-leverconnected with mechanism requiring to be started up and stoppedalternately at regularintervals. Still another use to which said powermay be applied is to engage and disengage one gear to and from anotherfor producing an intermittent motion to mechanism connected with thedriving-gear.

Many other ways of applying the power produced by my mechanical movementmay be adopted in addition to those above described.

In the present instance I have represented the traveling bodyhereinbefore described by means of a cam-roll, D, which is mounted on astud formed upon the crank-arm D of a'horizontal shaft, G. Said roll isarranged under or in line with the rock-lever A, and is held against thecam-surfaces A thereof by means of a spring, D, one end of which isfastened to the shaft G or passed around said shaftand arranged to bearupon the top of carriage G, as shown, while its other end bears upon theunder side of a pin, b,fastened in the crank-arm. The shaft G is fittedto turn in bearings G G, extending up from said carriage G, and

the latter is fitted to slide forward and back alternately in first oneand then the opposite directionin suitable ways or guides formed in thetable or bed H, as shown in Figs. 1 and 6. The aforesaid reciprocatingmotion may be imparted to carriage G in any well-known way, according tothe nature of the device or machine to which my invention is applied.'Ordinarily levers J, the upper ends of which are shown in Fig. 5, wouldbe employed for that purpose, the same being connected directly with orby means of links J with said carriage, as is also shown in said Fig.5.

In the first four figures of the drawings I have shown only such partsas are necessary to illustrate the practicability of my mechanicalmovement, while in the last four figures I have shown in additionthereto such parts as are necessary to illustrate the application ofsaid invention to a feeding device, this being one ofthe main purposesfor which the invention is designed in practiceviz., for feeding paper,envelopes, and other articles of a similarnature in the usual operationof printing, manufacturing, or otherwise operating upon the same. v

In the drawings the feeding device is designed for feeding forwardsheets of paper I from a pile of paper, I, placed in front of thegripping-jawsK of said device. I have shown three sets of said jaws. Thelower half or arm, F, of each jaw is made rigid upon the carriage G,while the upper parts, E, thereof are fastened to the rock-shaft G.Therefore it is obvious that when the carriage is moved s-forward andback, as hereinbefore described, the'upper arms, E, being operated bythe lever A through the cam-roll D crank-armD, and shaft G", the jawsare alternately closed and opened to grip and release the sheet of paperI in feeding the same forward, as hereinafter described and shown in thedrawings.

The operation of feeding forward a sheet of paper, I, by means of theaforesaid feeding device may be briefly summed up as follows: Assumingthat the left-hand end of lever A is locked, as shown by full linesFigs. 1, 4, and 6, and dotted lines'Fig. 8, and that the car- 'rro riageG and parts mounted thereon are moving from right to left toward saidlocked end of the lever, the jaws K being at this time closed, by acontinuation of said movement toward the left the cam-roll D comes incontact with the cam-surface of said lever, and is forced down as itcontinues to move forward, thus depressing the crank-arm D, and in consequence turning the shaft G a partial revolution,which operation, aswill be seen, causes the outer ends of the arms E (constituting theupper parts of the jaws) to be raised above the stationary arms F on thecarriage, thereby opening said jaws K to receive the sheet of paper 1.The latter may be raised from the pile I, so that the jaws may grasp it,or not only raised, but fed forward between the jaws in any well-knownway. As it matters not what way is adopted in practice to produce saidresult, and the same constitutes no part of my invention, I have simplyshown the positions of said paper in the drawings.

In Fig. 6 I have illustrated by dotted lines the jaws as being open withthe sheet of paper to befed forward between the upper and lower parts ofsaid jaws. As the carriage continues to move forward when the cam-rollcomes in contact with the locking-dog B, the latter is pushed forwardand disengaged from the end of the lever, thus allowing said roll to besprung up, when the jaws K are then closed upon the paper, ashereinbefore described and shown in Fig. 7 of the drawings. The aboveoperation not only closes the jaws K, but also by forcing up the end ofthe lever causes the opposite end thereof to be locked, as alsohereinbefore described and shown in Figs. 2, 3, 7,and 8, thus bringingarigid cam-surface in the line of travel of the cam-roll when reversed.Said reverse or return motion now takes place and the paper is drawnforward from the position shown by full lines to that shown by dottedlines in Fig. 7, where it is left by the.

jaws again opening and releasing the same by the cam-roll coming incontact with and being forced down by the rigid cam-surface at this endof the lever, as shown by full lines, Fig. 8. The roll shown by fulllines in said figure is represented as having arrived at the end of thelever in its movement toward the right and just ready to unlock said endof the lever. As it continues to travel forward, it pushes forward thedog 0, and thereby performs said unlocking operation, as in the formerinstance, at the opposite end of the lever. The movement of the carriageG is now again reversed toward the left,when the closed jaws are movedforward to grasp and feed forward the next sheet of paper, ashereinbefore described, and so on continuously for each succeeding sheetof paper. As the closed jaws move back for the next sheet, as aforesaid,they pass under the sheet previously fed forward, as shown by dottedlines in Fig. 8, the forward ends of said jaws being beveled back, asshown, to facilitate said operation.

Any convenient way may be adopted for controlling the movements of thelever A when unlocked, and its ends are sprung up by the cam-roll, ashereinbefore described. In this instance I have shown two stops, L L,for the above purpose arranged one upon each side of the pivot of saidlever. (See Figs. 1 andG.)

Having described my improved mechanical movement and one applicationthereof, what I claim as new and of my invention, and desire to secureby Letters Patent, is-

A mechanical movement comprising a rocking cam-lever pivoted betweenthe. extremities thereof, and adapted to be alternately unlocked andlocked at first one end and then the other by means of suitable lockingdevices, in combination with a traveling body having a reciprocatingmovement between said lever-locking devices adapted to unlock the latterand to press against the surfaces of the lever, substantially as and forthe purposes set forth.
